Abstract

The utility model relates to a heating device of a water dispenser, comprising a heating element part and an electronic control part, wherein the heating element part comprises a first heating wire, a second heating wire and a heating element base body, and the first heating wire and the second heating wire both are printed on the heating element base body in a thick film screen printing way; the heating element part also comprises a water inlet NTC, a medium water temperature NTC and a water outlet NTC, all of which are closely adhered to the surface of the heating element base body in a welding or crimping way; and the electronic control part comprises a relay control circuit, a thyristor control circuit and a central control circuit. The scheme provides the heating device of the water dispenser which is capable of saving the cost, reducing the complexity degree of the circuit and stably controlling the water outlet temperature.

Description

The water dispenser electro-heat equipment

Technical field

The utility model discloses a kind of water dispenser electro-heat equipment, further disclose heater and the electronic control system that precisely to control the instant heating type drinking machine of leaving water temperature.

Background technology

No matter existing water dispenser is single hot type or ice hot type, all requisitely is provided with heater, and produces hot water through Electric heating.

Two kinds of forms of heating and outer heating in the Electric heating that existing water dispenser adopts generally can be divided into.In external heating mode, traditional water dispenser hot water barrel all adopts the jacket type external heating mode, and this outer heater is that shape processes; Two heating wire devices are in the pore of heating collar; Adopt this mode, because the heating collar that is adopted is thicker, heats is poor; And it is complicated to exist locate mode and assembly structure, and causes problem such as waste of material.

And at present instant heating type drinking machine is influenced by inflow temperature and voltage ripple of power network to cause leaving water temperature inaccurate, thus the danger that children or old man's drinking-water are brought potentiality.

Summary of the invention

In view of above content, be necessary to provide a kind of and can save cost, reduce the complicated circuit degree, and can stablize the water dispenser electro-heat equipment of control temperature.

The utility model provides a kind of water dispenser electro-heat equipment, and wherein said device comprises heater part and electronic control part.

Preferably, said heater partly comprises heating wire, No. two heating wires and heater matrix, water inlet NTC, middle water temperature NTC, delivery port NTC, and a said heating wire and No. two heating wires are the printing heating wire.

Preferably, said water inlet NTC, middle water temperature NTC and delivery port NTC all are close to the heater matrix surface through the mode of welding or crimping.

Preferably, No. two heating wires are through relay control, and total power is exported.

Preferably, a heating wire is through controllable silicon copped wave control power output.Power variable through copped wave control heating wire is to reach delivery port temperature purpose accurately.

Preferably, one, No. two heating wire watt level is followed according to the flow size and is set to the Y watt, Y greater than 300 watts less than 3300 watts.

Preferably, said heater partly comprises controllable silicon electronic drive circuit, control relay circuit and central controller.

Compared with prior art, the advantage of the utility model is:

The electro-heat equipment of the utility model can be saved cost, reduces the complicated circuit degree, can stablize the control temperature through EMC and through thermistor easily.

Description of drawings

Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.

Fig. 1 is the schematic appearance of the utility model water dispenser electro-heat equipment.

Fig. 2 is the circuit theory diagrams of the utility model water dispenser electro-heat equipment.

The specific embodiment

The electro-heat equipment that sees also Fig. 1 and Fig. 2 the utility model is drawn together the two large divisions: the heater part; Electronic control part.

The heater part specifically comprises: 1, heater matrix; 2, heating wire; 3, No. two heating wires; 4, water inlet NTC; 5, middle water temperature NTC; 6, delivery port NTC; 7, controllable silicon; 8, controllable silicon drive circuit; 9, relay; 10, relay drive circuit, 11, central controller, also include A, first group of circuit tie point; B, second group of circuit tie point.

The specific embodiment is:

One, a heating wire 2 and No. two heating wires 3 are that the mode of leading to thick film screen printing is printed on the heater matrix 1.

Two, water inlet NTC 4; Middle water temperature NTC 5; Delivery port NTC 6; Through the welding or the mode of crimping be close to 1, the heater matrix surface.

Three, No. 2 heating wires 3 are through relay 9 controls, total power output.

Four, No. 1 heating wire 2 is through controllable silicon 7 controls, and the power variable through copped wave control heating wire is to reach delivery port temperature purpose accurately.

Five, detect inflow temperature when low as water inlet NTC 4, No. 1 heating wire 2 of controllable silicon 7 controls reaches setting value with more high-power output to guarantee delivery port NTC 6 detected leaving water temperatures.When water inlet NTC 4 detects inflow temperature when higher, No. 1 heating wire 2 of controllable silicon 7 controls is with smaller power output, to prevent the water outlet vaporization.

Six, middle water temperature NTC 5 is mainly used in and detects heater matrix surface temperature, prevents its dry combustion method.When there is water heater matrix 1 inside; NTC 5 detected temperature are about 120 degree; When the detected temperature of NTC5 is spent greater than 150, judge that heater matrix inside is anhydrous, be dry-fire condition; Then central controller 11 output control signals are given controllable silicon 7 and relay 9, break off the power supply of No. 1 heating wire 2 and No. 2 heating wires.

The utility model is primarily aimed at the improvement that the water dispenser heater is carried out; The above is merely the utility model preferred embodiment; Non-so promptly limit to the claim of the utility model; So the simple and easy variation and the equivalent transformation of doing with the utility model specification and graphic content such as all should be contained in the claim of the utility model.
